NAME

       coinst-upgrades - finding upgrade issues between to versions of a Debian distribution

SYNOPSIS

       coinst-upgrades [options] -o file control-file1 control-file2

DESCRIPTION

       coinst-upgrades  takes  as  input  two  Debian  control  files  corresponding to two versions of a Debian
       repository and output a report listing all packages that coult  be  installed  together  in  the  initial
       version  of  the  repository (specified by control-file1) and that can no longer be installed together in
       the final version of the repository (specified by control-file2), and explaining why they can  no  longer
       be installed together.

       If the control files are compressed, they will be automatically uncompressed by the tool.

OPTIONS

       --break sets
              Specify  that  some  packages does not have to be compatible any longer and that the corresponding
              issue should be omitted from the report.  The argument sets is a comma-separated list of  sets  of
              packages.  Each set is either a list of binary package names separated by a vertical bar symbol |,
              or a wildcard _ standing for any package.  We explain this option through examples.  You can write
              --break libjpeg62-dev to state that package libjpeg62-dev does not  have  to  remain  installable.
              But  it  is  usually  better to indicate that the package should remain installable but that it is
              fine if it is no longer installable with some other packages: --break libjpeg62-dev,_.  You can be
              even more precise and specify that two given packages can become incompatible, but that any  other
              incompatibility should be reported: --break parallel,moreutils.  Finally, you can use the vertical
              bar symbol to factorize several sets of packages: --break 'unoconv,python-uno|docvert-libreoffice'
              means  that  package  unoconv  does  not  have  to remain installable together with python-uno nor
              docvert-libreoffice.

       --debug name
              Activate debug option name.  Use --debug help to list available debug options.

       -help, --help
              Print a usage message  briefly  summarizing  the command-line options.

       -o file
              Write the report to this file.

       --popcon file
              Use popcon data from this file to order issues.
